hello,
this is the first topic in this forum and i happy for register here :-D
i have 2 prob. in "single phase induction motor" and i can't solve them
=======
=======
1)360 w , 220v , 50 hz , 4 pole , R(main)=6 , R(aux)=10 , X(aux)=14 , X(m)=48 , constant torque=.72 , rated speed=1440 rpm
determine: torque at full load
======
2) 120 v , .25 hp , 60 Hz , 1730 rpm , R(main)=2.4 , R(aux)=804 , X(main)=9.6 , X(aux)=3.2 , core loss=40 w , friction+additional=15 w , constant torque=.96
determine: input current , developed torque , efficiency
=======
=======
Resistance (R , X) by ohm
===================
===================
how can solve this with details
thank u :-D
